Trivia: In the early years of the series, Mulder is a firm believer in extra-terrestrials and Scully is skeptical. In real life this is the opposite, David Duchovny being the skeptic and Gillian Anderson the believer.
The "X-Files - Fox Mulder & Dana Scully Clip-on Prop / Cosplay ID Wallet Cards" is an excellent fit for fans of the X-Files TV show looking for authentic props or cosplay accessories.
